According to this piece published in the Conservative Judaism Journal, the Genesis creation story should not be taken literally. The role of science is to explain how and Judaism’s primary purpose should remain answering why. Instead, Genesis should be understood poetically and its main themes highlighted: “The world was made by a wise Creator who seeks man’s welfare, who created the world carefully with man’s benefit in mind, who created man with Godlike qualities and commanded him to administer the world wisely.”
If that is the case, how do we decide which parts to take literally? For example, Kosher rules are taken quite literally.
